KRONOS-327 was a Holowan Mechanicals-manufactured IG-86 sentinel droid, part of the IG-series of combat droids.[1] Possessing a masculine personality,[4] the droid was utilized by Ziro the Hutt as an assassin[2] and a bounty hunter.[5] As with other IG-86s in Ziro's service, KRONOS went large amounts of time without a memory wipe. As a result, the droid was able to gain substantial experience from his missions and even develop his own personality.[1] When KRONOS confronted Ziro following his failure on Yout 12, he asked for forgiveness from his master. As he was being dragged away by two other IG-86s, KRONOS verbally expressed his fear of being dismantled.[4]

KRONOS boasted a multi-sensor suite in his head, along with combat programming that aided in his targeting of opponents. He was knowledgeable in military tactics, and possessed many features that aided him in his missions—among them, magnetic graspers that clasped onto weapons, and servos that enabled him to move in high gravity. The droid commonly used an underworld blaster rifle.[3]
